I know they are ...ahem cost effective....but I have given last rites to 5 eMachines in the past 8 months. 3 of them were motherboard failures, one had a p/s fail twice and 1 of them would BSOD if you looked at it crosseyed and I had replaced memory, p/s, drives, ran thermal tests and still got random BSOD. Hate to say it but my Dells just sit and run quietly. I got 2 GX620's (older models) off eBay for about $175 ea and they are just fine for the weather station.
